Let *h* be a non-vanishing analytic function in the open unit disc with *h(0)=1*. Consider the class consisting of normalized analytic functions *f* whose ratios *f(z)/g(z)*, *g(z)/z p(z)*, and *p(z)* are each subordinate to *h* for some analytic functions *g* and *p*. The radius of starlikeness is obtained for this... Show more
